Problem mounting remote volume

I've got a few problems mounting a LUN on a remote server (CentOS 5.5, based on RHEL 5.5).

The server is connected through a Brocade HBA 415 and can see the remote ports correctly. I can even log into HCM Agent and see the LUN in the end of the tree.

The thing is that I cannot see a mounting point in the OS and cannot fdisk it (it displays "I don't know how to handle files with mode 2180" when trying to "fdisk /dev/bfa"). I know I have to format the disk prior to mount it (of course), but I don't know where the remote drive is located.

Although I still cannot see the volume in the system. Should it be available directly? The ECC agent is installed and running, but I'm not sure if it is needed anyway (there will be a single volume and a single path!).

Re: Problem mounting remote volume

I have multiple tools for reviewing the system status (lsscsi, bcu and so on).

I have verified that the system sees the LUN (through HCM Agent on a remote computer and through bcu). The thing is that a SCSI generic device is created succesfully (/dev/sg1) but no block device is understood after it. I don't know if there should be a specific driver installed or something. The Brocade driver + tools are correctly and fully installed (as stated in the documentation).

I understand that now that the system talks to the HBA and the kernel understands there is a SCSI device with a data stream (sg1) on the system, it should create the block device automagically.

I've tried the "sg3 utils" so I could map it manually, but they seem to be a little bit specific for me and find out they're not so useful at last.

The kernel messages ("dmesg") tell me the device is ok and everything is working, but compared to USB pendrive, the block device is never created.

I reinstalled the system to verify there is no driver overlapping, but behaves the same...
